Wireless networks (Wi-Fi, WLAN, Wireless) provide data transfer through radio waves which replace the wired cables used in regular wired networks.
The wireless network is composed of:
- an "Access Point" (sometimes called Hot-Spot) which is the unit connected to the wired network on one hand and on the other to the wireless network, and is built to serve multiple consumers at the same time
- adequate equipment on the user side, such as a laptop with a wireless communication card, capable of performing a wireless connection
The Technion network operates according to two communication protocols 802.11g and 802.11n (only in the Access Point units that support the standard).
The current maximum speed of data transfer over the wireless network is 54Mbps in the 802.11g standard and 270Mbps in the 802.11n standard.
By its nature, a wireless networks is of a lower security level than its wired counterpart, and therefore requires special attention to this issue, as detailed below.
Technion network services
There are currently three wireless networks on the Technion network: TechSec, Techpublic and eduroam.
Techpublic is a free network with no identification required.
TechSec and Eduroam are secure networks that require user identification.
Using the wireless network
The wireless network is intended for use by faculty staff, students and guests who own the required means of identification. Its aim is to enable free surfing without being dependent on static communication sockets.
This network is slower than wired network, so avoid transferring very large files or running applications that require ultra-broadband.
All instructions, rules and regulations applicable to the use of computers and the wireline network, are also valid for use on the wireless network.
eduroam - a global wireless network
eduroam is a global network that comprises worldwide higher education institutions. The network enables the academic community, faculty members and students an authorized access to the Technion from other academic institutions around the world. eduroam network provides students, researchers and staff of the institutions participating in the international project with an easy way to connect to the Internet from any network-connected place in the world (usually in academic institutions).
All it takes is a one-time registration to the service. Then you can operate the computer/mobile device (such as a cellphone or a tablet) using the username and password supplied to you by your own institution.
Installation and Configuration - following are instructions for connections to the wireless network:
First time connection to the wireless network
- Windows 7 users (Hebrew) Wi-Fi WIN 7 HEB
- Windows XP users (English) Wi-Fi WIN XP ENG
- MAC users (English) Wi-Fi Mac ENG
The connection requires using a "Secret Code". Staff members who do not have a secret code may contact their faculty support staff to generate one for them.
Security - Wireless technologies are considered relatively unsafe. Several technologies, such as wireless phones, microwave, and bluetooth, use the frequencies of 2.4 Ghz and 5 Ghz. These devices can interfere with wireless communication. Wireless network radio waves can be caught by unauthorized parties.
At this point, after the identification process, the data traveling on the Technion wireless network is not encrypted, unless a secured application is used.
It is very important to make sure that your computer is updated and that operating system patches and signature files are updated to the latest antivirus software.
Guests - Authorized by faculty guests may connect to the wireless network after having coordinated this with the faculty support staff.
Mailing List - You can receive updates related to the wireless network at the Technion. For subscription, click here.
Support - For questions or support, please read first the wireless FAQ. if you didn't manage to find an answer to your questions, you may open a call in our helpdesk system or send e-mail to email@example.com
Are you within range? Try to improve your location relative to the Access Point.
Are you allowed to use the network? Have you used username and password?
For new user settings, please click here.
Can other people in the region connect? If many people can not connect, there is probably a general problem not related to your PC. You can open a call at the Support Center.
Email - Use only a system that allows secure (encrypted) login process such as Webmail
Working Online - Do not go to sites that require identified login (username and password), unless they allow for secure login (look for the word https instead of http at the beginning of the URL and also for the icon of a closed padlock).
Transfer files - Use only a software that allows secure work (for example: SFTP, WinSCP3).
Continued development of the wireless network will also include the encryption of information transmitted over it.
